Frame Time
What does this counter show?
This counter represents the average time it has taken the GPU to process a frame (in seconds) over the selected period.
It's worth noting that this value is not calculated per CPU process, i.e. if there are two processes using the GPU to render, the average frame-time over the course of a second will be the average frame-time of both processes during that period of time.
What does a high value mean?
The larger this value is, the longer it takes on average for the GPU to render a frame. It's worth noting that this average includes all processes utilising the GPU during the selected time period so if a second process is running alongside the application you want to profile, e.g. OS composition, then this will affect the average frame time value.
